The present invention concerns a vise having apairof jaws for clampinga piece of work and a1so.having a member between said jaws that can serve as a support forwork clamped between the jaws .orcan, be adjusted to serve as an alternate Jaw.

.Another object is to provide a vise having a fixed. jawand a pair of alternate movable jaws whereby selection ofthe-movable jaw to be used forclamriing.aparticular.piece of work can be made consistent withthe size of the piece of work.

.Another objectis to provide a vise having a fixed jaw and amovable head provided with a jaw and supporting a member between the jaws which can serve as a support for relatively large pieces of work clamped between the jaws or can be adjusted to serve as an alternate jaw for clamping relatively small pieces of work against the fixed jaw.

Further objects and advantages of this invention, as well as'its construction, arrangement and operation, are apparent'from the following description and claims in connection with the accompanying drawings, in which:

Fig. l is a side elevational view of a preferred form of the invention with the vise conditioned to hold a relatively large piece of work and with the member between the jaws adjusted to serve as a work support;

.Fig. 2 is a top, plan view of the construction shown in Fig. 1;

Fig. 3 isa side 'elevational view of the form of the invention shown in Fig. l but with the vise conditioned to hold ,a, relatively small piece of work and with the member between the jaws adjusted to serve as an alternate jaw;

Fig. 4 is-a view similar to Fig. 1 showing a modification of the inventiomand,

Fig. 5 is a view similar to Fig. 2 showing the modified form of invention seen .in Fig. 4..

There is shown inFigs. 13 a vise it suitable for holding a workpiece for gang milling or slicing operations including a frame I 2 that is a relatively large and heavy member having an anchor flange 13 by which the vise can be secured to any suitable support. Flange i3 is provided with periph eral slots M5 for receiving suitable anchoring members. Disposed above frame i2 is an elongated body |5 upon which is mounted transversely at one end a fixed jaw block l6. Secured to jaw block It by screws i1 is a jaw l8 vcomprisingan elongatedmember extending transversely ofbody t5 and having formed at its upper end work-gripping surfaces iii-and 2d. Jaw i8 is so dimensioned of Marchli, 1883, as

Offset upwardly at the opposite end. of body. I5 is .a-vertical flange ..2l .disposed transversely of body. -Formed. in. flangell is a bore 22 into whicha collar-231s frictionfitted. Mounted for turningmovement in collar 23 is a rod 2A having externalthreads 2.5. .O-neextremity 25 of rod 24 canbemengaged by any suitable mechanism to effect turning of rod 24 within flange 2|. The other extremityof rodZd is-threaded into the end of a movable .head..2l that ismounted for sliding movement on sliding .ways 28 formed in the upper surface. of frame l5. Movable head 21 is an elongated member extending longitudinally above frame I5 andhaving a top surface 2;! and end surfaces 30 and.3.l.

Formed. in the upper surface ofmovable head 2! .is a dovetail slot 32 extending transversely across the entire .width of movable head 21. -riittedinto dovetail slot321 is a jaw that has its lower end offset to form a dovetail 34 designed to mate. inslot 32in movable head 21. Screws 35 lock jaw 33 relative to movable head 21. The upper surfaceof jaw-133 is:offset to form workgripping surfaces fit-and 37!, substantially similar to. gripping surfaces ill' and 20, respectively, of jaw is and jawsl8 and 33 are arranged in opposed relation so that a piece of work 38 can be clamped therebetween.

Detachably-mounted on end iii of movable head 2? is asupport 39 securedin place by' means of screws 40. -.Support 39 extends transversely of that grippingsurfaces-iil and 25 extend above 555 block l6 as shown in Fig. 1.

frame l5.and.-is. provided with a work-supporting surface ll; atrthe top thereof. Work-supporting surface is disposed in the-same plane as gripping surfacezll of fixed 'jaw'ls and gripping surface 3'! of jaw 33. Thus, work-supporting surface 4| is flush with the bottom surface of workpiece 38; and -serves tosupportworkpiece 38 against sagging betweenyjaws l8 and 33.

InFlg. 3. is-shown the construction illustrated in Fig. 1 with-modifications presently to be described uvhereby-avise H: is arranged to clamp a relatively. small-piece ofwork 38a. Parts in Fig. 3 that are identical with; those in Fig. 1 are indicated by identicalreference characters.

In Fig; 3, support 39:.i's removed and replaced by jaw'42- thatis securedzin-place against end 3| of movable head 21'by'means of screws 40. Jaw $2 is similar to jaw lfliandbis provided at its upper end with work=grippingsurfaces 43 and 44 that are in opposed relation .to'zwork-gripping surfaces is and: 2030f gjaw 1! ii. .The relatively" small piece of worlcfiiidcis clamped" between jaws l8. and. 42.

Support 39 of Fig. 1 and jaw-142 of Fig. 3 are used alternately depending onthe: size of the work piece to be clampedin vise l I. When not in use,

jaw 42 can be stowed on fixed jaw block 16 by means of screws 45 as seen in Fig. 1 and support 39 when not in use can be stowed upon fixed jaw block it by means of screws 45 as seen in Fig. 3.

Figs. 4 and 5 show a modification of the form of invention illustrated in Figs. 1 to 3. Parts that are identical with those shown in Figs. 1 to 3 are given identical reference characters. Mounted on face 3| of movable head 21 is a work-engaging member 46 mounted for rotary movement upon a screw 41. One end of member 46 is formed to provide a work-supporting surface 48 and the opposite end of member 46 is formed to provide work-gripping surfaces 49 and 53. With member 46 in the position disclosed in Fig. 4, surface 48 is disposed in a position to support workpiece 38. Member 46 can be inverted to bring gripping surfaces 49 and 59 into a position to clamp a work-piece against fixed jaw 18.

Operation of the device is as follows. When it is desired to clamp a relatively large piece of work in vise H in the manner indicated in Figs. 1 and 2, rod 24 is rotated to cause threads 25 thereon to effect sliding of movable head 21 along sliding ways 28 until jaw 33 is withdrawn a distance from fixed jaw 18 that corresponds approximately with the length of the piece of work that it is desired to clamp. Member 39 is then secured to face 3| of movable head 21 by means of screws 40 so that surface 4| thereof is suitably disposed between jaws 33 and 18 in a position to support the piece of work. A workpiece 38 is then laid upon surfaces and 31, respectively, of jaws I8 and 33 in which position work piece 38 rests upon work supporting surface 41. Rod 24 is then rotated to cause threads thereof to move sliding block 21 on sliding ways 28 toward fixed jaw 18 until workpiece 3B is gripped securely between surfaces 19 and 36, respectively, of jaws l8 and 33.

When it is desired to clamp a relatively small piece of work in vise H as shown in Fig. 3, support 39 is removed from face 3! of movable head 21 and is replaced by jaw 42. Rod 24 is rotated to cause threads 25 thereof to effect sliding of movable head 21 on sliding ways 28 until the distance between jaws l8 and 42 is approximately correct for accommodating a workpiece 38a which is then laid upon work gripping surfaces 26 it of jaws I8 and 42, respectively, and rod 24 is turned to cause movable head 21 to slide on sliding ways 28 until work piece 38a is securely gripped between surfaces 19 and 43 of jaws 8 and 42, respectively.

In the form of invention shown in Figs. 4 and 5, the operation is similar to that described in Figs. 1 to 3 except that a single work-engaging member 46 is used and can be rotated about supporting screw 41 to bring surface 48 into operative position for supporting a relatively long piece of work or to alternately bring gripping surfaces 49 and 5!] into operative position for clamping a relatively short piece of work.

It is to be understood that various modifications and changes can be made in this invention without departing from the scope thereof as set forth by the appended claims.

The invention described herein may be manufactured and used by or for the Government of the United States of America for governmental purposes without the payment of royalties thereon or therefor.
